HAIR CLIBPEBJ.

e pileafio marital-c1. 24, 1928. Serial no. 264,557.

This invention relates to hair clippers. One' object is to provide a clipper that will automatically so shade the cut that no line of demarcation between long and short cuts will be discernible. A further object is to provide such a clipper wherein the normally automatic mcchanisn' can,"at will,'be 'subjected to manual control and be'causedfto produce a cut to conform tothe will or desire of the operator.

With the foregoing and other objects in View the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed'out in the claims and illustrated in" the accompanying drawings which form a part of'this application folpatent, and in which? Fig. 1 is a perspective view of a hair clipon line 6 6 of Fig. 5.

Fig. 6 is a vertical sectional view taken Like reference characters denote corre spending parts throughout the several views Electric hair clippers now in general use require a certain amount of skill on the part of the operator for high class work. The

cost of the services of a skilled barber is today no'small matter to large families and in many communities it is not always convenient, even atthe prevailing prices, to obtain such se'vices. V I

This invention is designed to enable one totally unskilled in the art of high class hair cutting to perform a good job, also tofurnish skilled barber's with a device thatwill enable them to do quicker, more accurate and neater work.

The machine comprises a comb that serves as a support for the ordinary electric clipper, the lower blade of the clipper being lengthened to facilitate its attachment to and operation by the comb. The clipper, proper, gslidably mounted the some upon the inclined upper face thereof in such manner that as the machine is moved over the head upward from the back of the neck the clipper first cuts the hair veryshort and then gradually longer, Manually operable means are provided, however, whereby the sliding movement of the clipper proper may be arrested so that uniform length cutting may be had when desired.

The reference numeral 1 denotes a pair of hair clippers comprising the movable blade 2 reciprocally mounted to the stationary blade 3 which blade is somewhat wider than" the blade 2 to provide for itsrelative movement, said blade 3 being materially lengthened as shown to permit the application" of the attachment; The lengthened blade 3 is rormed longitudinally of its under face" 1' with the spacedtracks' 5,6 along its opposite lateral edges, said racks vextending almost, but not quite, from end to end of the blade .so that short non-toothed portions 7 are formed at the rack ends.

. v The comb attachment comprises a casing havingthe opposed sides"8,-9, connected by the integral end portion 10, base 11 and the bevelled or inclined face 12, the sides 8, 9' rising above the base llfand face 12 and being then bent inwardly or towardeach other so that diametrically opposedgrooves 13, 1e are formed immediately above the.

face 12. The extended portions of the sides 8, 9 are less extensive than the face 12 or base 11, the said side extensions at one end terminating in the bevelled shoulderslt'; that terminate flush with the face 12.

Longitudinally extending parallel slots 16 are provided in 'the face 12 andv bas'e'll whereby to form. teeth 17, the said teeth beingcurved or rounded smnewha't at their free ends, the inner ends of spaced a substantial distancefrom the end 10 of the casing. Thebase 11 of the casing is formed with a transvm'sev perforation 18 to afford clearance for the roller 19 keyed to V the shaft 20 that extends transversely of the casing and is journaled in the sides thereof, said roller projecting below the base 11 as shown. p I

' Also keyed to the shaft '20jfbetween the ends of the roller 19 and the sides of the casing are the small gears 21, .22 in mesh the slots 16 being with. the relatively large 24. loose engagement with the per proper,

being cut thus cutting upon shaft 25 that is parallel with the shaft ous to the casing with. the oppositely disposed hooks 28, said hooks 28 normally being in alignment with the grooves 13, 14: so that they may receive and serve as guides for the blade 30f the clipper as it moves outwardly {from the comb. A spring 29 connecting the handles 27 serves yieldingly to retain them in the adjusted spaced relation.

\Vhile the hooks 28 are normally in alignment with the grooves 13, let thehandles 27 diverge outwardly from said hooks so, that the blade 3 as moves out will come in between them and afford clearancefor the hand of theoperator supporting the handles.

In operationthe clipper proper is'placed upon the comb casing with the blade 3 in recessed sides of the casing, the forward end of the blade 3 being fiusli withthe forward or free ends of the teeth 17 of the comb, The gears 23, 24 now are in mesh with the racks 5, 6. The clipper isnow placed so that the free ends of the teeth 17 will be disposed upon the back of the neck' where the hair cutting operation The current is now turned on causing the clipper to operate. The ma chine is moved slowly over the head. The roller 19 will travel over the neckand head and slowly, through gears 21, 22, 23, 24: and the racks 5, 6 cause the blade 3, and the clipto ride outwardly and rearwardly fromtheface 12 of the comb casing. The hair being cut extends' up between the teeth "17 of the comb and is engagedby the blades 2, 3. As the blade '3 moves outwardly over the bevelled face 12 it gradually gets farther and farther'away from the hair the hair gradually longer and longer as the clipper is guided by the handles 27 over the head.

To cut the hair at any desired length uniformly instead of gradually shorter the operator may at any time press the handles 27 together causing them to arrest the movement of the blade 3 thus locking the gears, racks and roller. The cutting operation will now be performed as before by the blades 2, 3 except that there will be "no movement of. the blade 3 relative to the casing face 12. j When the blade 3 is moved forward until the gears 23, 24 pass beyond the terminal teeth of the rack the relative is to begin.

-movement of the blade 3 will then cease and blades,

the clipper will be in initial or starting posi tion again.

NVhat is claimed is 1.'The combination with a hair clipper, of blades, racks formed upon one blade, a comb comprising a; casing formed with a bevelled toothed faceto'recei've said blade, a roller in said. casing projecting below the base thereof, gearing operatively connecting said roller and rack whereby to cause movement of said b'lade'relative to said casing, means for retaining said blade and casing in operative'relation, handles, movably secured to said casing, and guide clamps carried by said handles for operative association with said blade.

2. The combination with ahair clipper, of blades, racks formed upon one blade, a comb comprising a casing formed with a bevelled toothed face to receive said blade, the sides of'said casing slidably engaging said blade, a roller in said casing projecting beyond the base thereof, gearing operatively connecting said roller and rack whereby to cause movement of said blade relative tosaid casing, handles movably secured to said casing, and blade-engaging means carried said handles. I

3. The combination with a hair .clipper,of one blade being extended and formed with spaced longitudinally extending racks, a comb comprising a casing formed with a bevelledtoothed' face to receive said'blade, 'a roller in saidcasing and extending transversely thereof and in spaced relation to said teeth,'gearing operatively connecting said roller and racks whereby to cause movement of said blade relative to said casing, means for retaining said bladeand casing in operative relation, handles movably secured to said casing, and hooks integral with said handles contiguous to said casing.

1-. The combination with a hair clipper, of blades, one blade being extended and formed with spaced longitudinally extending racks, a comb comprising a casing formed with a bevelled toothed face to re ceive said blade, the sides of said casing beingektended upwardly beyond thetop face thereof to receive said blade, a"roller'1n said casing, gearing operatively connecting said roller and rack whereby to cause movement of said blade relative'to said casing, hooks contiguous to and normally in alignment with the' upwardly extended sides of said casing,and"liandles cz'rrrying said hooks and movably secured'to-said casing, said handles diverging and extending upwardly as they extend outwardly from said hooks with respect 'to "said casing;

lntes'tiniony that I claim the'foregoing as my own'I have hereby aflixed my signature.
